Using data from six years of i3 cohorts, we present in this paper a qualitative and quantitative evaluation of the program in terms of student learning, research production, and graduate school enrollment. We find that students who participate in i3 report significant learning gains in information-science- and graduate-school-related areas and that 52% of i3 participants enroll in graduate school, over 2 $$\\times $$ × the national average. Based on these and additional results, we distill recommendations for future implementations of similar programs to address underrepresentation in information science."); - List resultPhrase = fetcher.performSearch("name:\"Redmiles David\""); - List result = fetcher.performSearch("name:Redmiles David"); + List resultPhrase = fetcher.performSearch("author:\"Redmiles David\""); + List result = fetcher.performSearch("author:Redmiles David"); // Phrase search should be a subset of the normal search result.
